Positioning of the structures plays an important role regarding the welding procedure. There are structures that can be welded in several positions, while other can be welded in one or two specific positions. Overhead welding is one of the most common positions in the field.
In order to cope with the requirement and difficulties of overhead welding position, we have found out that the Optrel VegaView 2.5 which you can check here, is the perfect choice as far as welding helmets are concerned.
During time, several methods have been used, developed and applied in order to allow welders work in every available position for better and more effective results. A welding procedure can be characterized by the position of the welding joint or the structure.
There are four basic positions used by the welders. These positions are:
- Flat position
- Vertical position
- Horizontal position
- Overhead position
These are the positions most commonly applied in the welding field, and there several methods used to take advantage of them in order to achieve successful weldings.
Like with all welding techniques, wearing the appropriate headgear is obligatory to ensure the safety of the welder. In this article, we recommend 5 of the most suitable welding helmets for overhead welding in the market, analyzing their advantages and disadvantages.
Overhead welding definition
The overhead welding position is considered the most difficult one for many reasons. The main one is the fact that the welder has to work against gravity, which is one of the natures most brutal and hard-to-defeat forces.
Overhead welding position is fairly inconvenient too. You have to look upwards and keep the welding torch or stick stable during the process, in order to achieve precise welding joints. Although it is a fact that overhead welding is the most difficult in contrast to the rest of the positions, there are methods that can help the welder achieve high quality results.
During welding with the particular position, you have to keep in mind that there are some things you have to be careful of. For instance, to protect yourself from molten metal, flames and debris while being under the welding area, acquiring and welding coverall suit like the Red Kap Men’s Twill Action Back Coverall would be the ideal solution.
How to weld properly in overhead welding
The main difficulty of the overhead welding is the fact that the molten metal has the tendency to fall due to gravity and causes drops or sages to the bead. The welder overcomes the particular difficulty by keeping their welding puddles as small as possible, preventing gravity to make them fall down.
In addition to this, filler metal is added into the joint in order to make it stick together and make the joint even stronger. This way, the bead is protected and reinforced, and the result is a more sustainable welding joint.
Welders need to control the temperature of the metal at all times, to avoid making it molten and saggy. They need to take the time and let it freeze when appropriate, so that the pieces of metal stick together before the welding arc hits them again.
Experienced welders, know that the best way to achieve successful results in overhead welding is by melting equally both sides of the welding joint, using their torch. If this method isn’t enough, additional filler metal should be added to the joint for extra reinforcement like mentioned before.
Because there is need for small puddles in order to avoid damaging the joint, only one rod must be used during the process. The welder should take control of the temperature of the weld at all times, and provide the appropriate time to the metals to freeze and stick together.
Overhead welding techniques
There is a variety of techniques that can be used during overhead welding. The general rule, is that the welding torch should be held at a 90 degrees angle in accordance to the welding area. This way you can keep the torch or stick stable, and protect yourself from flames and molten pieces of metal.
In order to achieve successful welds while in overhead position, you are going to need to use the travel angle. Travel angle means that you will have to move the electrode towards the direction of the weld, while holding it (usually) at a fifteen degree angle.
In order to make a weave bead while you are in the overhead welding position, you need to weave forwards and backwards several times, until you achieve the weld you desire. This is mainly a task for more experienced welders, although beginners can do it too after they take some time to practice.
When welding in this position, it is recommended that you move the torch a bit faster when you reach the end of the weave. This way, you use more force to the welding area, and the pieces of metal tend to stick better because you hit them with the welding arc.
What is more, by moving the torch or the stick faster, you gain better control of the filler metal inserted into the joint, while it is at a deposition state. Keep in mind that you need to have full control of the weaving and not move it too fast, to avoid overheating the metal and making the puddle bigger than the desired size.
What are the right welding helmets for overhead position?
As stated above, overhead position is probably the most difficult one in the welding field. It requires a certain level of experience and lots of practice to become fully accustomed with the appropriate techniques that will lead you to successful results.
As far as welding helmets for overhead welding are concerned, they need to meet some criteria which will allow the welder to work conveniently on his welding projects. Like all welding helmets, they must meet all the National Safety Standards to begin with.
Additionally, helmets for overhead position should protect the neck effectively. This is because, during the overhead welding the welders work against gravity. For this reason, they need to prevent debris and flames from hurting their neck and face.
Large viewing area is also a characteristic that appears to be extremely useful for overhead welding. Helmets with large lenses allow welders to have better control of their working environment, and make as little moves as possible. This is especially helpful for restricted areas with limited space.
